HI I have just bought a Bentley Arnage red Label 6.75 I have just covered 175 miles to a full tank which has got to be wrong!!!! I also own a rolls shadow II with the same engine size and previously owned a Bentley Turbo R none of which are or were as bad as this. SO if anyone can tell me whether this is right or not I would love to hear from you if you have any ideas as to what might be causing this problem I would love to know what it is.
Thanks for your assistance in advance.
